Goal

Create a visual dashboard and integrative analysis platform that provides consistent and robust supporting evidence for use in:

  • Prioritization of targets nominated by individual AMP-AD projects.
  • Nomination of targets supported across AMP-AD projects.
  • Compilation of AMP-AD evidence for use by research community to evaluate other targets of interest.

Approach

  1. Develop prototype.
  2. Build alpha platform based on user feedback, focusing on gene-based queries for nominated AMP-AD targets.
  3. Expand to include genes across the transcriptome (partnership with Josh Shulman @ Baylor).
  4. Expand to provide entry points based on gene, protein, network, or variant queries.

Anticipated users: AMP-AD consortium and affiliates, MODEL-AD consortium, external AD researchers

User experience interviews

Understand how our users will interact and utilize the Wall of Targets application - usages, pain points, gaps, and preferences.

Performed think aloud exercise - use the application and state what you are doing and what you are thinking as you use the prototype.

10 participants, including 4 industry/pharma and 3 mouse model system researchers

Interviews - what we learned

  1. Biological context
  2. Druggability vs. tractability
  3. Nominations and source of evidence
  4. Consistency and reproducibility across cohorts
  5. Ranking and comparison
